Scribblenauts not loading on CycloDS

I downloaded Scribblenauts, and it worked fine on my CycloDS v1.55. Today, however, when I try to load the ROM, my Cyclo freezes and doesn't load the ROM. I tried redownloading the ROM, but it didn't work. Does anyone know how to fix this?

Backup your files and format your MicroSD. Then reload the games.

It worked! Thanks!
